こんにちは、私が直面している問題は、以下のアラートビューを作成しようとしましたが、次のようなエラーが発生することです。単項式に対して無効な引数タイプ「void」。行の読み取り:-(void)alert1:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)ButtonIndex {Cheers
time.text = @"0";
[timer invalidate];
NSString *timemessage = [NSString stringWithFormat:@"Unlucky! You survived for %i seconds!", timenumber];
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"You've Been Caught!" message:timemessage delegate:nil cancelButtonTitle:@"Try Again" otherButtonTitles:@"Show Leaderboard", @"Submit To game Center",nil];
[alert1 show];
-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)ButtonIndex {
if (ButtonIndex == 1) {
GKScore *myScore = [[GKScore alloc]
initWithCategory:@"*****"];
myScore.value = timenumber;
}
}
}}
